DUSHANBE, December 30, 2008, Asia-Plus — In Tajikistan, work of Tethys Petroleum Limited (Tethys) has been focused on meeting Tajikistan”s short term needs for gas whilst carrying out workovers and re-development activities on existing fields and discoveries. Work is underway on the Komsomolsk gas field close to Dushanbe and on the Khoja Sartez gas condensate field in Khatlon’s Kulob region.
According to press release issued by Tethys on December 29, gas has now been successfully tested from the Khoja Sartez 22 well (KJZ22) at estimated rates (based on wellhead pressures) up to 80,000 cubic meters per day on a 12mm choke with a flowing tubing head pressure of some 40 atmospheres — these rates are subject to verification when more accurate metering equipment arrives onsite.
The gas bearing interval was identified by the use of modern cased hole wireline logging techniques including the use of a pulsed neutron-neutron (PNN) log. Arrangements are underway for supply of this gas to the Kulob gas distribution company, for use in the local market in the Kulob area. Test gas has now been successfully flowed to the Kulob gas measurement station and a gas sales contract is being negotiated.
The Khoja Sartez gas condensate field is located on the north east flank of one of the several large salt domes in the Kulob area, and Tethys believes that there is further potential both for additional gas production from existing wells, and from deeper, as yet undrilled horizons within the structure, and around other parts of the Khoja Sartez salt dome.
